Yes, limit access to police agencies, courts, defense attorneys and proscutors
No, we have a right to know about a person's criminal record.
Certain capital offenses should never be expunged, however. It needs to strike some sort of balance between reintegrating and rehabilitating criminals with their potential harm to society. Someone who is arrested for smoking dope shouldn't have a drug charge following him/her around the rest of their life. Someone is who is convicted of forcible (not statutory) rape or child molestation on the other hand, shouldn't even be seeing the light of day in the first place. But that is another matter.
For example, only 11 states require a person to be 18 before they can consent to sex and in several of those there is no close-in-age defense. Therefore, in some of them if a person aged 18 has sex with a person aged 16, they can be charged with one or more sex offenses. Interestingly, 16 is the age of consent in 31 states and the District of Columbia, while 17 is the age of consent in the remaining 8. So you can see just crossing a state line can lead to something that is legal in one state being illegal and registerable in another. There are more examples of differing things that place a person on the sex offender list without being either a pedophile or serial rapist, but I don't need to go into those.
My preference is to identify offenders that are a true threat and either keep them in prison, or send them to a mental facility..don't send them back out into society. But if the system releases a person back into society, I believe they deserve the presumption that they are rehabilitated and should be given the chance to re-integrate.
"A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself. For the traitor appears not a traitor; he speaks in accents familiar to his victims, and he wears their face and their arguments, he appeals to the baseness that lies deep in the hearts of all men. He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist. A murder is less to fear"
Cicero Marcus Tullius
i'm fairly uncomfortable with the current state of background checks for employment. it's a serious disincentive for people to turn their lives around once released. maybe a better solution would be to have the records searchable for five years or so, and then they go private. you keep your nose clean long enough, and then you can get a good job.
A Canadian conservative is one who believes in limited government and that the government should stay out of our wallets and out of our bedrooms.
